With the arch of the new springs you have probably changed the caster angle. Caster helps the wheel center itself. You should have something like 0-1 degrees positive caster,but that's just a guess. You may be able to find degree shims to install between springs and frt axle. Other than shims there's not too much you can do about it.
Does it have a slight wander when going down the road? Or the steering not feel as tight as it did b4? like your chasing it.
